Tim Abbott d180f7ccfc right sidebar: Clean up rendered description logic.
Previously, we were masking the realm_description raw Markdown with
rendered Markdown, which was a type error.

When we switch to calling /register explicitly in a few commits, this
results in a bug, since the raw Markdown ends up taking priority.

Fix this by just using a different name for this different concept.

yogesh sirsat 08e8a21da0 custom_profile_fields: Clarify an external account error message.
This error message is for a very precise situation -- the pattern not
having the desired format. We should say that, rather than a generic
"Malformed".

NerdyLucifer 6a5d646739 settings (admin/org): Show error for same choices in "list of options".
Currently an user can create multiple options with same text/label in
the select/"list of options" custom profile field type.

Fix this issue by extending the validator to throw an error if there
are duplicate choices in the "list of options" in custom profile
field.

Tweaked by tabbott to use a simpler check.

Fixes: #21880

Sahil Batra 9a6886f630 users: Always pass delivery_email in user's own object.
This commit changes the code to always pass delivery_email
field in the user's own object in 'realm_users'.

This commit also fixes the events sent by notify_created_user.
In the "realm_user/add" event sent when creating the user,
the delivery_email field was set according to the access
for the created user itself as the created user was passed as
acting_user to format_user_row. But now since we have changed
the code to always allow the user themselves to have access
to the email, this bug was caught in tests and we fix the person
object in the event to have delivery_email field based on whether
the user receiving the event has access to email or not.

Sahil Batra aa98b39429 bulk_create: Copy realm-level defaults in bulk_create_users.
This commit adds code to copy the realm-level default of
settings while creating users through bulk_create_users.

We do not directly call 'copy_default_settings' as it
calls ".save()" but here we want to bulk_create the objects
for efficiency.

We also add the code to set realm-default of enter_sends as
True for the Zulip dev server as done in 754b547e8 and thus
we remove enter_sends argument from create_user_profile as
it is of no use now.

Anders Kaseorg c263bfdb41 queue: Use a thread-local Pika connection.
According to the documentation: “Pika does not have any notion of
threading in the code. If you want to use Pika with threading, make
sure you have a Pika connection per thread, created in that thread. It
is not safe to share one Pika connection across threads, with one
exception: you may call the connection method add_callback_threadsafe
from another thread to schedule a callback within an active pika
connection.”

https://pika.readthedocs.io/en/stable/faq.html

This also means that synchronous Django code running in Tornado will
use its own synchronous SimpleQueueClient rather than sharing the
asynchronous TornadoQueueClient, which is unfortunate but necessary as
they’re about to be on different threads.

Lauryn Menard d2207d4ad5 backend: Add `org_type` to realm settings updates and events.
`org_type` already exists as a field in the Realm model and is
used when organizations are created / updated in Zulip Cloud,
via the `/analytics/support` view.

Extends the `PATCH /realm` view to be able update `org_type` as
other realm / organization settings are updated, but using the
special log / action that was created for the analytics view.

Adds a field to the `realm op: update` / `realm op: update_dict`
events, which also means an event is now sent when and if the
`org_type` is updated via the analytics view. This is similar
to how updates to an organization's `plan_type` trigger events.

Adds `realm_org_type` as a realm setting fetched from the
`POST /register` endpoint.

Alex Vandiver 56058f3316 caches: Remove unnecessary "in-memory" cache.
This cache was added in da33b72848 to serve as a replacement for the
durable database cache, in development; the previous commit has
switched that to be the non-durable memcached backend.

The special-case for "in-memory" in development is mostly-unnecessary
in contrast to memcached -- `./tools/run-dev.py` flushes memcached on
every startup.  This differs in behaviour slightly, in that if the
codepath is changed and `run-dev` restarts Django, the cache is not
cleared.  This seems an unlikely occurrence, however, and the code
cleanup from its removal is worth it.

Alex Vandiver 04ca2e92f7 caches: Cache link preview data in memcached, not in PostgreSQL.
The choice to cache these in the database dates back to c93f1d4eda,
with the comment added in da33b72848 while working around the
durability of the "database" cache in local development.

The values were stored in a durable cache, as they needed to be
ensured to persist between when they were inserted in
`get_link_embed_data` and when they were used in
`render_incoming_message` via `link_embed_data_from_cache`.

However, database accesses are not fast compared to memcached, and we
wish to avoid the overhead of the database connection from the
`embed_links` worker.  Specifically, making the connection may not be
thread-safe -- and in low-memory (and Docker) configurations, all
workers run as separate threads in a single process.  This can lead to
stalled database connections in `embed_links` workers, and failed
previews.

Since the previous commit made the durability of the cache no longer
necessary, this will have minimal effect; at worst, posting the same
URL twice, on either side of an upgrade, will result in two preview
fetches of it.
2022-04-15 14:48:12 -07:00
Alex Vandiver 351bdfaf78 preview: Use cache only as a non-durable cache, not an IPC.
The `get_link_embed_data` / `link_embed_data_from_cache` pair as
introduced in c93f1d4eda uses the cache
as a temporary store inside of the `embed_links` worker; this means
that it must be durable storage, or the worker will stall and re-fetch
the same links to preview them.

Switch to plumbing through the fetched URL embed data as an parameter
to the Markdown evaluation which uses them, rather than using the
cache as an intermediary.  This frees up the cache to be merely a
non-durable cache.

As a side-effect, this removes get_cache_with_key, and
link_embed_data_from_cache which was its only callsite.
2022-04-15 14:48:12 -07:00
Alex Vandiver 327ff9ea0f preview: Use a dataclass for the embed data.
This is significantly cleaner than passing around `Dict[str, Any]` all
of the time.

Zixuan James Li 9d448e73d2 decorator: Remove cachify in favor of lru_cache.
`cachify` is essentially caching the return value of a function using only
the non-keyword-only arguments as the key.

The use case of the function in the backend can be sufficiently covered by
`functools.lru_cache` as an unbound cache. There is no signficant difference
apart from `cachify` overlooking keyword-only arguments, and
`functools.lru_cache` being conveniently typed.

Alex Vandiver 3af2c8d9a3 timeout: Warn if the thread did not exit.
As noted in the docstring for this function, the timeout is
best-effort only -- if the thread is blocked in a syscall, it will not
service the exception until it returns.  It can also choose to catch
and ignore the TimeoutExpired; in either case it will still be running
even after the `timeout()` function returns.

Raising a vare TimeoutExpired it still somewhat accurate, but obscures
that the backend thread may still be running along merrily.  Notice
such cases, and log a warning about them.

Alex Vandiver e714264756 timeout: Re-raise from where the TimeoutExpired hit the thread.
Having just thrown an exception into the thread, it is often useful to

instance.

Tim Abbott d149af936d models: Rework Attachment.is_*_public to be a cache.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.

This pattern meant that neither field was updated in situations where
the access permissions for a message changed:

* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.

This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.

To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.

Alex Vandiver 4f93b4b6e4 uploads: Skip the outgoing proxy if S3_KEY is unset.
When the credentials are provided by dint of being run on an EC2
instance with an assigned Role, we must be able to fetch the instance
metadata from IMDS -- which is precisely the type of internal-IP
request that Smokescreen denies.

While botocore supports a `proxies` argument to the `Config` object,
this is not actually respected when making the IMDS queries; only the
environment variables are read from.  See
https://github.com/boto/botocore/issues/2644

As such, implement S3_SKIP_PROXY by monkey-patching the
`botocore.utils.should_bypass_proxies` function, to allow requests to
IMDS to be made without Smokescreen impeding them.

Alex Vandiver 1ac0035f8c markdown: Allow whitespace overlaps in topic linkifiers.
`prepare_linkifier_pattern`, as of db934be064, adds a match to the
end of the regex, of either the end of string, or a non-word character
-- this is in place of a negative look-ahead, which is no longer
possible in re2.  This causes the regex to consume trailing
whitespace, and thus not be able to match twice in succession with
`pattern.finditer` -- "#1234 #5678" fails to match because the space
is consumed by the first match of the regex.

Rather than use `pattern.finditer`, write own own version, which
rewinds over the non-word character consumed after the match, if any.
This allows the same "after" non-word character to also satisfy the
"before" of the next match.

Fixes #21502.

resolving a topic.

in complexity.

Alex Vandiver 62ba8e455d CVE-2022-24751: Clear sessions outside of the transaction.
Clearing the sessions inside the transaction makes Zulip vulnerable to
a narrow window where the deleted session has not yet been committed,
but has been removed from the memcached cache.  During this window, a
request with the session-id which has just been deleted can
successfully re-fill the memcached cache, as the in-database delete is
not yet committed, and thus not yet visible.  After the delete
transaction commits, the cache will be left with a cached session,
which allows further site access until it expires (after
SESSION_COOKIE_AGE seconds), is ejected from the cache due to memory
pressure, or the server is upgraded.

Move the session deletion outside of the transaction.

Because the testsuite runs inside of a transaction, it is impossible
to test this is CI; the testsuite uses the non-caching
`django.contrib.sessions.backends.db` backend, regardless.  The test
added in this commit thus does not fail before this commit; it is
merely a base expression that the session should be deleted somehow,
and does not exercise the assert added in the previous commit.

Steve Howell 822c232e37 message flags: Extract create_historical_user_messages.
A user can subscribe to a stream and sometimes (depending
on stream permissions) see messages from the stream
that were sent before they subscribed, and that user
won't have a UserMessage row for that message.

In order to do things like star a message, we need
to create UserMessage records on the fly.

In the past we wisely constrained this logic to the
specific use cases. But I think we can generalize
the logic now.  For example, we are now building a
feature to mark messages as unread, and it motivates
the same need to auto-create UserMessage rows.

So now we handle this in a more generalized fashion.

Alex Vandiver c2f2863d37 push_notifications: Remove access control on "remove" notifications.
When removing notifications, we skip the access control on if the user

because they have already done so.

Tim Abbott d693a6717c i18n: Remove quote syntax from stream description notification.

While we're changing this, also standardize on the "```` quote" style
of quote blocks to ensure code/quote blocks in stream descriptions are
unlikely to conflict with this syntax.

Alex Vandiver 3264361f63 push_notifications: Set a timeout on FCM requests.
In steady-state, requests to FCM take about a second; however, in
cases where the remote FCM server is unstable, the request has been
observed to block for more than a minute.

As noted in the previous commit, pushes must complete within 30s;
fail fast, and let the retries and exponential backoff handle errors.

The worst-case total time taken with timeouts and errors for an FCM
notification is 19.5s.  Unfortunately, `aioapns` does not appear to
have any timeouts, and thus this commit cannot guarantee a total of
fewer than 30s.
2022-03-08 12:52:58 -08:00
Alex Vandiver f531f3a27f push_notifications: Drop FCM retries to 2, not 10.
This reverts bc15085098 (which provided
not justification for its change) and moves further, down to 2 retries
from the default of 5.

10 retries, with exponential backoff, is equivalent to sleeping 2^11
seconds, or just about 34 minutes (though the code uses a jitter which
may make this up to 51 minutes).  This is an unreasonable amount of
time to spend in this codepath -- as only one worker is used, and it
is single-threaded, this could effectively block all missed message
notifications for half an hour or longer.

This is also necessary because messages sent through the push bouncer
are sent synchronously; the sending server uses a 30-second timeout,
set in PushBouncerSession.  Having retries which linger longer than
this can cause duplicate messages; the sending server will time out
and re-queue the message in RabbitMQ, while the push bouncer's request
will continue, and may succeed.

Limit to 2 retries (APNS currently uses 3), and results expected max
of 4 seconds of sleep, potentially up to 6.  If this fails, there
exists another retry loop above it, at the RabbitMQ layer (either
locally, or via the remote server's queue), which will result in up to
3 additional retries -- all told, the request will me made to FCM up
to 12 times.

Since we've changed the database to contain these new fields, we just

by removing `prev_subject` from edit history API.

Adds an API changelog feature update for the renamed `prev_subject`
field (to `prev_topic`) and new fields (`topic` and `stream`)
in the message `edit_history`.

Also, documents said `edit_history` in the `MessagesBase` schema
in the api documentation, which is used by the `/get-messages`,
`/get-events` and `/zulip-outgoing-webhooks` endpoints.

Fixes #21076.

Also, when passing invite_expire_in_days as an argument

Alex Vandiver a40b3e1118 realm_emoji: Stop swallowing all exceptions from upload_emoji_image.
Putting all of the logic in a `finally` block is equivalent to a bare
`except` block, which silently consumes all exceptions.

Move only the most-necessary parts into the except; this lets
`BadImageError` exceptions from `zerver/lib/upload.py` to escape,
allowing better the generic "Image file upload failed" to be replaced
with a more specific message.

It also allows unexpected exceptions, as the previous commit resolved,
to escape and 500.  This lets them be detected and resolved, rather
than give users a silently bad experience.

Alex Vandiver 96a5fa9d78 upload: Fix resizing non-animated images.
5dab6e9d31 began honoring the list of disposals for every frame.
Unfortunately, passing a list of disposals for a non-animated image
raises an exception:
```
  File "zerver/lib/upload.py", line 212, in resize_emoji
    image_data = resize_gif(im, size)
  File "zerver/lib/upload.py", line 165, in resize_gif
    frames[0].save(
  File "[...]/PIL/Image.py", line 2212, in save
    save_handler(self, fp, filename)
  File "[...]/PIL/GifImagePlugin.py", line 605, in _save
    _write_single_frame(im, fp, palette)
  File "[...]/PIL/GifImagePlugin.py", line 506, in _write_single_frame
    _write_local_header(fp, im, (0, 0), flags)
  File "[...]/PIL/GifImagePlugin.py", line 647, in _write_local_header
    disposal = int(im.encoderinfo.get("disposal", 0))
TypeError: int() argument must be a string, a bytes-like object or a
number, not 'list'
```

`check_add_realm_emoji` calls this as:

```
    try:
        is_animated = upload_emoji_image(image_file, emoji_file_name, a
uthor)
        emoji_uploaded_successfully = True
    finally:
        if not emoji_uploaded_successfully:
            realm_emoji.delete()
            return None
        # ...
```

This is equivalent to dropping _all_ exceptions silently.  As such,
Zulip has silently rejected all non-animated images larger than 64x64
since 5dab6e9d31.

Adjust to only pass a single disposal if there are no additional
frames.  Add a test for non-animated images, which requires also
fixing the incidental bug that all GIF images were being recorded as
animated, regardless of if they had more than 1 frame or not.

Tim Abbott 1a46df40c3 resolve topic: Limit unread flag on automated notifications.
Previously, users found it annoying that the automated "Resolve topic"
notifications triggered an unread for everyone in the stream; this
discouraged some users from using the feature on older threads for
fear of being annoying. We change this to a better default, of only
users who participated in the topic (via either messages or reactions)
being eligible for the new message being unread.

We will likely want to create global and stream-level notifications
settings to control this behavior as a follow-up -- some users, like
me, might prefer the simpler "Always unread" behavior in some streams.

Note that the automated notifications that a topic was resolved will
still result in the topic being moved to the top of the left sidebar.
This would be somewhat difficult to change, since the left sidebar
algorithm just looks at the highest message ID in the topic.

Fixes #19709.

Anders Kaseorg 90e202cd38 docs: Consistently hyphenate “web-public”.
In English, compound adjectives should essentially always be
hyphenated.  This makes them easier to parse, especially for users who
might not recognize that the words “web public” go together as a
phrase.

Mateusz Mandera 4102816240 upload: Pass the target realm to create_attachment.
The target realm was not being passed to create_attachment in
upload_message_file implementations. This was a bug in the edge-case of
cross-realm messages - in particular, causing a bug in the email
gateway:
When an email with an attachment is sent, the message is mirrored to
Zulip with Email Gateway Bot as the message sender and uploader of the
attachment. Due to the realm not being passed to create_attachment, the
Attachment would get created with .realm being the system bot realm,
making the attachment inaccessible under some conditions due to failing
the following condition check (that's expected to pass, provided that
the .realm is set correctly):
```
    if (
        attachment.is_realm_public
        and attachment.realm == user_profile.realm
        and user_profile.can_access_public_streams()
    ):
        # Any user in the realm can access realm-public files
        return True
```

Lauryn Menard a832a8a3af api_docs: Fix enum strings in parameters to have quotes.
Fixes the rendering of enums to show strings with quotation marks,
while integers will continue to be rendered without quotation marks.

This allows for an empty string to be passed as an enum value and be
rendered as such in the documentation. Null will be rendered without
quotation marks, like integer values.

Lauryn Menard aaa627229e api: Update `update_message` event required fields.
Makes `edit_timestamp` and `user_id` required fields for all
`update_message` events.

Adds `rendering_only` as another required field to signal if
events are only updating the rendered content of the message,
which is currently the case for adding inline url previews.

Updates `test_event.py` so that `do_update_message` and
`do_update_embedded_data` refer to the same testing schema
for `update_message` events, and therefore reflect the same
required fields for the `update_message` event.

The OpenAPI definition for `update_message` events is also
updated to reflect the required field and descriptions of
various properties are updated for the addition of the
`rendering_only` property.

Eeshan Garg 0d99809fd3 streams: Add notifications for permission policy changes.
The change to curl_param_value_generators.py warrants a brief
explanation. Stream permission changes now generate a notification
message. Our curl example test for removing a reaction comes after
the two tests for updating the stream permission changes, thus the
hardcoded message ID in that test needs to be incremented by 2 to
account for the two notification messages that now come before it.

This is a part of #20289.
